How SSI panels are recruited
Respondents are recruited from thousands of sources to maximize reach and representation. SSI’s recruitment
policy is broad in scope and is combined with multiple quality controls and checks to ensure all potential respondents
are eligible to take a survey.
SSI’s blend methodology increases consistency and representivity
Because sources are not only different from each other, but can also change over time, SSI uses a combination of
personality and psychographic characteristics to understand and identify the underlying traits which impact the way
people answer survey questions.
By controlling the characteristics of people within the sample, based on asking them a short set of key questions, SSI has created an online sample blend which is exceptionally consistent when measured by comparison with external benchmarks, including telephone sample studies and industry measures such as the Grand Mean.
The SSI Blend is continuously monitored and calibrated by a dedicated team of methodologists and analysts.
